本文主要研究下springboot2的embeded container的配置改动
springboot 1.x
import org.apache.catalina.connector.Connector;
import org.apache.coyote.ProtocolHandler;
import org.apache.coyote.http11.Http11NioProtocol;
import org.apache.tomcat.util.threads.ThreadPoolExecutor;
import org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer;
import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;
import org.springframework.boot.context.embedded.tomcat.TomcatConnectorCustomizer;
import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory;
import org.springframework.boot.web.servlet.ErrorPage;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Component;
@Component
public class EmbeddedTomcatConfig implements EmbeddedServletContainerCustomizer{
@Override
public void customize(ConfigurableEmbeddedServletContainer container) {
TomcatEmbeddedServletContainerFactory factory = (TomcatEmbeddedServletContainerFactory)container;
factory.addConnectorCustomizers(new TomcatConnectorCustomizer() {
@Override
public void customize(Connector connector) {
Http11NioProtocol protocol = (Http11NioProtocol) connector.getProtocolHandler();
protocol.setMaxConnections(200);
protocol.setMaxThreads(200);
protocol.setSelectorTimeout(3000);
protocol.setSessionTimeout(3000);
protocol.setConnectionTimeout(3000);
}
});
}
}
通过实现org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer的customize方法来实现自定义
springboot 2.x
import org.apache.catalina.connector.Connector;
import org.apache.coyote.ProtocolHandler;
import org.apache.coyote.http11.Http11NioProtocol;
import org.apache.tomcat.util.threads.ThreadPoolExecutor;
import org.springframework.boot.web.embedded.tomcat.TomcatConnectorCustomizer;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.boot.web.servlet.server.ConfigurableServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.Ordered;
import org.springframework.stereotype.Component;
@Component
public class EmbeddedTomcatConfig implements WebServerFactoryCustomizer<ConfigurableServletWebServerFactory> {
@Override
public void customize(ConfigurableServletWebServerFactory factory) {
((TomcatServletWebServerFactory)factory).addConnectorCustomizers(new TomcatConnectorCustomizer() {
@Override
public void customize(Connector connector) {
Http11NioProtocol protocol = (Http11NioProtocol) connector.getProtocolHandler();
protocol.setMaxConnections(200);
protocol.setMaxThreads(200);
protocol.setSelectorTimeout(3000);
protocol.setSessionTimeout(3000);
protocol.setConnectionTimeout(3000);
}
});
}
}
在2.x版本改为实现org.springframework.boot.web.server.WebServerFactoryCustomizer接口的customize方法
小结
springboot1.x的相关类如下:
- org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer
- org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer
- org.springframework.boot.context.embedded.tomcat.TomcatConnectorCustomizer
- org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory
springboot2.x的相关类如下:
- org.springframework.boot.web.servlet.server.ConfigurableServletWebServerFactory
- org.springframework.boot.web.server.WebServerFactoryCustomizer
- org.springframework.boot.web.embedded.tomcat.TomcatConnectorCustomizer
- org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory
对比一下可以清楚看到相关的改动
